The cost of cosmetic dentistry depends on the degree of misalignment of the teeth and can range from a few thousand dollars to around $40,000. Orthodontics is a form of treatment for malocclusion in which the teeth are straightened and the appearance is improved. Orthodontics can be performed during the period of tooth replacement, and early orthodontic treatment can achieve better results. Early orthodontics takes advantage of the growth and development of children to improve the development of the jaws and match the development of the teeth to the development of the jaws for the purpose of tooth reshaping. Mainly for children with jaws that are underdeveloped, early interventions such as arch expansion promote the development of the jaws, provide sufficient position for the teeth, and reduce the possibility of misshapen jaws. Early active braces are about $4,000 to $5,000, and treatment ends in about three months to six months. After the end of the period of tooth replacement, orthodontic treatment can be used for tooth reshaping. If the jawbone can accommodate all the teeth, orthodontic treatment can be performed without tooth extraction. If the jawbone cannot accommodate all the teeth, orthodontic extraction is required. There are traditional orthodontic treatments that involve bonding brackets to the teeth and using archwires to force the teeth to move them into alignment, which costs about $10,000 or so. Invisible orthodontics is about $40,000. So orthodontics costs about five thousand dollars for early orthodontics and between ten thousand and forty thousand dollars for fixed orthodontics.
